Hypertension is a modifiable cardiovascular risk factor and displays a rapidly growing incidence due to aging and the acquisition of an unhealthy lifestyle. Hypertension is linked to the development of target organ damage in several vascular beds such as coronary arteries, peripheral, cerebral, and renal arteries. Besides, along with the presence of other cardiovascular risk factors, it aggravates vascular dysfunction due to the aging process. The mechanisms of vascular dysfunction in hypertension are complex and involve excessive salt intake and water retention, activation of neurohormonal systems, induction of endothelial dysfunction of large arteries and microcirculation, development of arterial stiffness, and complex interactions with cellular pathways of inflammation, oxidative stress, and thrombosis. The extent of vascular dysfunction in patients with hypertension can be assessed by evaluating endothelial function, measuring arterial stiffness, and testing the levels of circulating biomarkers of oxidative stress, pro-inflammatory cytokines, and thrombosis. Assessing these markers in subjects with and without hypertension could aid in identifying those at risk of vascular damage and improving risk prediction for future cardiovascular events. While several lifestyle and pharmacological therapies have shown promise in addressing vascular dysfunction in hypertension, none of these biomarkers have been established as an independent risk factor or treatment target. Therefore, in this article, we review the literature on the evidence that exists regarding the role of vascular dysfunction in the pathophysiology, diagnosis, progression, and treatment of hypertension, highlighting the lack of conclusive evidence in this field.
